Coldest morning this fall so far, 2C (36F) and somewhat windy but clear. I dressed for it with warmer gloves, a cycling jacket and tights. I didn't wear a hat or other head covering and wondered if this was wise but my head got warm through the ride so I was fine. Tomorrow mornings forecast however is 0C (32F).

Installed a new front tire over the weekend, a Michelin Pilot Sport (700x32). I wasn't sure what the puncture-resistance rating of it was but I looked it up this morning and it seems to be ok. I reinstalled my Schwalbe Marathon on the rear because it is a little fatter and therefore, might be a little softer on the butt: it is a 700x35 but, compared with the Michelin and the tire on my road bike, the Marathon appears narrower and "taller", somewhat aerodynamic which might explain why its ERTO code is 37-622 rather than 35-622, the Michelin Pilot Sport tire is 622-32 which makes sense because it appears more round than the Marathon.

Due to construction on two parts of my route, I've had to take detours which allow me to add 6km to my route for a total of 22km (13.7mi) each way.
